GAS-REGULATOR.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed May 4, 1909. Serial No. 493,938.

To all whom i-t may concern:

Be it known that I, LoUIs H. MILLER, a citizen of the United States, residing at Mount Eden, in the county of Alameda and State of California, have invented a new and useful Gas-Regulator, of which the following is a specification, in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a gas regulator and its object is to provide a suitable gas pressure for lighting purposes from a pressure very much higher and variable.

An object of the invention is to produce a simple and yet eifeetive regulator which will be cheaply constructed, and which will require the smallest number of parts, and` almost no parts with which unexperienced persons can tamper.

Another object of the invention is to produce a regulator which will require no guides for the gas bell, the regulating valve being secured to the top of a pipe near the top of the gas bell and in such a position with respect to the top of the bell that no guide more than the guides of the valve is necessary.

In the drawings in which the same numeral of reference is applied to the same portion throughout, Figure l is a central vertical section of the regulator, Fig. 2 is a plan view of the regulating valve, Fig. 3 is a side elevation of the regulating valve, Fig. l is a vertical central sectional view of the regulating valve, and Fig. 5 is a hori zontal sectional view of the regulating valve on the line 5v 5 of Fig. 4.

The numeral l is applied to the base of the regulator to which the side 2 of the water tank is secured. In the center of the base is screwed the pipe 3 to which a T is -secured the object being to provide more than one outlet for the gas from the source of supply, as where two pressures are to be used, as is common in the use of acetylene, with which this regulator is especially intended for use.

On the top of the pipe 3 is secured the regulating valve 4, said valve being constructed of two portions 5 and 6 which are screwed together near the center of the completed valve. In the portion 5 there is a guide 7 for the valve stem 8, and in the bottom of the part 6 there is a diaphragm which acts as the valve seat, and near the top of the part 6 is a guide 9 the same as the guide 7 the upper portion of the valve being provided with a series of outlet openings for the escape of the gas from the high pressure pipe to the gas bell 10. 'Ihe top of the valve acts as a rest for the gas bell and also as an additional guide for the valve stem, since the continual thrusts of the gas on the under side of the bell cause it to move up and down during the time the gas is owing from the machine, and since the Inotion is very small the bell can rest on the top of the valve at any time when it is necessary for the valve to be almost full open. A weight W of any desired size may be placed on the top of the gas bell to regulate the pressure therein, a large weight increasing the gas pressure and a small one decreasing it, the lowest pressure being that which will raise the gas bell without a weight on the top thereof. The gas is drawn to the pipe through which it is to be used through the pipe 11 which passes through the bottom of the water tank, any suitable connections being threaded to said pipe.

The main advantage gained in the use of this regulator lies in the fact that the central pipe supports the regulating valve so close to the under side of the gas bell that no other means than the valve is necessary to guide the movement of the bell, and when the bell is down it rests on the flat top of the gas bell, all the weight being taken off the valve stem.

I-Iaving thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is as follows:

In a gas regulator, a water tank having openings in the bottom thereof, an outlet pipe passing through one of said openings and to a point near the top of the tank, an inlet pipe passing through the other of said openings, a valve body on the upper end of the inlet pipe, a valve disk having a stem projecting through the top of the valve body, and a gas bell secured on the valve stem and adapted to be seated on the top of the valve body when the valve is wide open.

In testimony whereof I have set my hand this 27th day of April A. D. 1909, in the presence of the two subscribed witnesses.
